Nonpoint Source Pollution from Agricultural Drainage: Impacts and Innovations in California
This paper provides an overview of the more significant impacts of agricultural drainage in California, and describes the role of the State's Agricultural Drainage Water Management...
Arid Zone Hydrologic Implications for the Proposed Yucca Mountain Repository
The U.S. Department of Energy (DOE) has chosen Yucca Mountain, Nevada for characterization to determine if it is suitable to become the Nation's first High-Level Radioactive...
Chemically-Enhanced Treatment: An Alternative to Biological Secondary Treatment for Ocean Outfalls
Chemically-enhanced treatment is a process whereby chemicals are added to wastewater in order to enhance solids removals through coagulation. This treatment process can obtain removal...
The Effect of Grain Size Distribution on the Entrainment of Interstitial Water into Overland Flow
Non-point source pollution from agricultural runoff is an important environmental problem. This experimental study considers the effect of media heterogeneity on the entrainment of interstitial...
Integration of GIS, Remote Sensing, and Digital Elevation Data for a Hydrologic Model
The Agricultural Nonpoint Source Pollution Model (AGNPS), which was developed by Agricultural Research Service, was used as a test model for assessing nonpoint source pollution. The model...
Evaluation of the Potential for Release of Residual Coal Tar by Flood Scour at a Superfund Site
To address the potential for release of residual coal tar by flood scour, stream cross-sections, stream discharge and sediment grain size data were collected during the Remedial Investigation...
Use of Geogrids on Soft Deposits
The construction of highway embankments over soft and waste deposits required the use of geogrids as an economical alternate to conventional methods of 'remove and replace'....
Waste Geotechnics and Geosynthetics
The geotechnology related to waste management focuses around assessing the movement of water and pollutant transport, containment of the pollutant so that it is unable to pollute the underground...
Design of a Lined Landfill on Compressible Clays
In mid-August, 1989, a 500,000m3 landslide occurred at a commercially operated landfill in central Maine. The landslide material consisted of municipal...
Geocomposite Waste Cell Capping System for Steep Slopes
Several geosynthetics manufacturers have developed new products with high surface friction characteristics for capping steep slopes. One such product has been developed that will satisfy...
Geocomposites Simplify Methane Barrier/Venting System Design
A case history describing the use of a geomembrane and geocomposite to simplify the design of a combined subsurface barrier and venting system is presented. The passive barrier and venting...
Site Assessments
The 1986 Superfund Amendment and Reauthorization Act (SARA) established an innocent purchaser defense applicable if a new owner conducts appropriate inspection and appropriate inquiry...
The Dredging Dilemma
Disposal of dredge materials is becoming a national environmental problem. Disposal sites on land are becoming extremely scarce and environmental objections growing. There are also objections...
Instrumenting for Eternity (Almost)
Prendergast describes the safety features and instrumentation for a low level radioactive waste disposal facility planned for Illinois. Federal law requires that each state or group of...
The New Geotech: Geoenvironmental Engineering
Technical, societal and business forces will continue to dictate the course of professional practice throughout the 1990s. The author's firm, begun in 1965 to practice soil...
Cleaning Up: The Second Decade
Endless media coverage and a high level of public anxiety make it seem as though the U.S. has been attempting to clean toxic waste sites for decades. In fact, the 1980s were our first...
Strategic Sanitation Planning
Conventional sewerage has generally been the only method considered for human waste and wastewater disposal in urban areas, both in developed and developing countries. In developing countries,...
Advanced Integrated Wastewater Pond Systems
By incorporating special environments for methane fermentation and photosynthetic oxygenation, advanced integrated ponding systems attain high degrees of primary and secondary treatment...
The Impact of Agricultural and Industrial Development on the Water Quality in Latin America and the Caribbean
Agricultural and Industrial development are having a serious negative impact upon the quality of water resources in Latin America and the Caribbean. The continuing demographic explosion...
Heavy Metals Sources and Waste Minimization for a POTW
This paper presents a summary of recent studies conducted to minimize heavy metals discharged to a South San Francisco Bay Publicly Owned Treatment Works (POTW). The studies identified...
